BULLET-MOLD.

SPECIFICATION forming part" of Letters Patent N 0. 748,460, dated December 29, 1903. Application filed September 21, 1903. Serial No. 174,092. (No model.)

To all whom it may concern.-

Beitknown that I,J OHNW. ANDERSON, J r.,a citizenof the United States, residing at Woodland, in the county of Iroquois and State of I Illinois, have invented a new and useful Bullet-Mold, of which the following is a specification.

This invention relates to improvements in bullet-molds.

The principal object of the invention is to provide an improved form of bullet-mold by which the time and labor required in the operation of molding bulletswith hand-molds may be materially reduced.

A special object of the invention is to provide in a hand bullet-mold novel means for cutting ofi from the base of the bullet the sur-' plus metal and ejecting it from the mold.

With the objects above stated and others in view, as will appear when the invention is more fully disclosed, the same consists in the construction and combination of parts of a bullet-mold, hereinafter described, illustrated in the accompanying drawings, forming part of the specification, and having the novel features thereof specficially pointed out in the appended claims.

1 In the drawings, Figure 1 is a plan view of the bullet-mold in position to receive molten lead, the hand of the operator being indicated in dot-and-dash lines in association with the mold and the open position of the moldmembers being indicated by dotted lines. Fig. 2 is'a plan view of the mold with the parts in the position taken when thecut-oft device is operated. Fig. 3 is a view from the side with the parts in the position shown in Fig. 1. Fig. 4 is a view in side elevation of the member 1, showing the form of the cavity in the mold. Fig. 5 is a plan view of the mold with the cut-off device detached therefrom and the spring for keeping the mold-sections normally apart removed. Fig. 6 is adetail view in section through the cut-E plate.

Referring to the drawings in which corresponding parts are designated by the same characters of reference, 1 and 2 represent two members pivoted intermediate oftheir ends and each provided at one end with a mold-section, the mold-sections being designated 3 and4, respectively. The member 1 has a straight handle portion recessed at out.

lever 6.

for the reception of the lever-arm ,6, which is pivotally mounted thereon, as shown, and is provided. near its end with a ring 7, the utility of which will afterward be pointed The member 2 is outwardly curved, as shown, and is held normally in the position indicated in dotted lines in Fig. 1 by means of a spiral spring 8, interposed between members 1 and 2 near their pivotal point. The mold-sections 3 and 4 are substantially alike, and when members 1 and 2 occupy the positions indicated in solid lines in Fig. 1 the inner faces of the mold-sections contact to present a complete mold having a metalreceiving cavity 9, in which the bullet is formed. it

Pivotally mounted on the top of mold-section 4 is a plate 10 of the same area as the top of the mold. The plate 10 is provided in the middle with an opening 1l,which is preferably funnel-shaped, as best shown in Fig. 6, and presents at the bottom a sharp edge which is capable of acting as a shear to cut away the surplus metal at the base of a bullet. Pivotally attached to the plate 10, on the upper side thereof, is a link 12, having at the end attached to the plate a laterally-projecting lug 13. The link 12 is pivoted at its other end to the end of the lever ,6 which is mounted in the recess 5 on the member 1. The lever 6 is normally held in the position shown in solid lines in Fig. 1 by a spring 14 abutting against a boss 15 on the member 1 and the inner curved face of the The outward movement of the lever 6 under the influence of the spring is limited by contact of ashoulder on the lever with one end of the recess 5, in which the lever is mounted, and the contact of the lever with the recess holds the lever in such position that the pivoted plate 10, which is connected with the lever, as already explained, by means of the link 12, is held in the position shown in solid lines in Fig. 1, with the opening 11 above the cavity 9 of the mold.

' In using the mold the parts will be held at the start in the position indicated by solid lines in Fig. 1, the mold being grasped with the left hand, and the little finger beinginsorted into the ring 7 at the end of the member 1. The member 2 will then lie next/the thumb, and the pivoted lever 6will be en- IOO gaged by the three fingers between the thumb and little finger. At the beginning of the operation of molding a bullet, however, the three fingers engaging the lever 6 will be relaxed, so that the lever may be held by the spring at the outward limit of its movement, the fingers being kept from slipping forward too far on the outer surface of the lever by the projection 17 on the outer surface of the lever. The little finger will be contracted to hold the members 1 and 2 as close together as possible, so that the two mold-sections 3 and 4, carried by said members, will contact to form a complete mold. Melted lead will be poured through the opening 11 in the plate 10 to fill the cavity 9 of the mold, and as soon as the mold is filled the molten lead will solidify. The three fingers resting upon the lever 6 will then be contracted, forcing the lever inward to the positionshown in Fig. 2, compressing the spring 15 and through the connecting-ling 12 turning the plate 10 upon its pivot to the position shown in Fig. 2.

:The movement of the plate over the top of the mold will be sufficient to shift the opening 11 in the plate entirely to one side of the cavity in the mold, and the sharp edge at the bottom of the opening will sever from the finished bullet the surplus lead on the base thereof. At the same time the change of the relative positions of the plate 10 and the link 12 will bring the lug 13 on said link up to the margin of the opening 11 and will cause the dislodgment of the surplus metal from the plate. When the parts of the mold have all been brought into the position shown in Fig. 2, the operation of molding will be completed, and the bullet may be released from the mold by merely relaxing all of the fingers. The springs 8 and 14 will act at once to separate the members 1 and 2 and to swing the lever 6 to its outer position. When the members 1 and 2 are separated to the full extent, the mold-sections 3 and 4 will be far enough apart for the bullet to drop downward between them into any suitable receptacle, preferably a vessel containing water for cooling.

From the foregoing description it will be clearly seen that with the mold constructed in accord with this invention the operation of molding bullets may be materially expedited, for the solidification of the metal within the mold takes place practically instantaneously, and the removal of the surplus metal from the base of the bullet and its ejection from the mold, which ordinarily require more time than any other step in the operation of molding bullets, may be effected as soon as the cavity of the mold is completely filled. It will also be observed that the parts of the mold are so designed that they will all lie easily within the hand of the operator, and the movements of the hand necessary to effect the removal of the surplus metal and the discharge of the completed bullet from the mold can be made with the greatest ease. The inward movement of the lever 6 to sever the surplus metal from the base of the bullet in the mold is the only part of the operation which ever requires any considerable muscular effort, and if the operation is performed quickly the efiort required even for this step is inconsiderable. As, however, considerable force is necessary when the metal has become thoroughly soildified, it is desired to limit the inward movement of the lever 6 by providing a positive stop therefor, so that the lever may not be caused to move farther than is necessary. For this reason the end of the member 1 is formed on a curve corresponding to the curvature of the inner face of the lever 6, and the lever is so formed that when the plate 10 has been moved a sufficient distance to sever completely the surplus metal from the bullet the lever will contact with the end of the member 1, as shown in Fig. 2.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, 1s
